HETEROGENEOUS CATALYST COMPOSITION FOR POLYMERISATION OF ISOPRENE, METHOD FOR PRODUCTION AND USE THEREOF

摘要

FIELD: chemistry.SUBSTANCE: said composition is a reaction product of the following three components: A) a titanium halide, B) an organoaluminium compound, primarily consisting of alkyl aluminium of general formula AlR, and C) an electron donor consisting of a polyether of general formula RO(RO)R(I) and/or a tetrahydrofurfuryl ether of general formula(II).Values of radicals R, R, Rand Rare given in the claim. The molar ratio of component B to component A is in the range of 0.01-10:1 and the molar ratio of component C to component B is in the range of 0.001-10:1. The invention also relates to a method of producing said heterogeneous catalyst composition and to a method of polymerising isoprene using said composition.EFFECT: obtaining a catalyst for polymerisation of isoprene with high activity and improved properties of the obtained polymer.16 cl, 2 ex
